Big-headed ants Pheidole megacephala from southern Africa use a different tactic, relying on the super-sized heads and jaws of their major workers. For numbers and for carnage it was an Austerlitz or Dresden.
Arguably the most aggressive tramp ant species is the red imported fire ant Solenopsis invictaoriginally from South America, but now found in North America, Australia, China, Hong Kong, Taiwan, the Philippines and some Pacific and Caribbean islands. Known by its sinister-sounding acronym RIFA, the species is infamous for its burning sting.
The Battle of the Ants is not a stand-alone essay. Such evolutionary adaptations are fascinating; but in the wrong place they are just the advantage needed to dominate an ecosystem, with devastating consequences.
But ultimately, with an unparalleled appetite for aggression and a billion dollar charge for criminal damage, the red imported fire ant is currently the least-wanted ant on the planet. To truly rid an environment of these invaders, near-military operations have been executed.
In honeypot ant colonies, specially adapted workers known as repletes store sugar and protein solutions in their swollen abdomens which can grow to the size of a cherry. Where supercolonies build their nests, roads and pavements are disturbed which inflates maintenance bills.
But aphids, scale insects and mealybugs are themselves voracious eaters, sucking sap from the plants upon which they live, destroying them. Once inside they chew through the insulation on cables and short out circuits by bridging electrical contacts.
Local conservationists are concerned by the sharp decline in lizard populations linked directly to this dietary change. Ants are very small. On the islands of Hawaii, where there were no native ant species to stop their spread, residents are warned that little fire ants can blind pets with their stings.
It is simply an excerpt. However, Argentine ants, which have invaded parts of the region, do not.
The island is known for its diverse fauna and flora including the distinctive red land crabs. Advertisement And they are losing the battle. In clashes with other invaders RIFA are known to overpower Argentine ants with their venomous sting but they are no match for their original South American neighbours, the tawny crazy ants Nylanderia fulva.
To reduce collateral damage, pest controllers often use baits to attract the ants to a final carbohydrate feast laced with poison.
The invaders effectively farm these plant-destroying insects, protecting them from predators. If they produce more honeydew than the ants can eat, the excess sugary solution can encourage mould to grow on vegetation, leading to further degradation as seen in the forest canopy of Christmas Island.
Yellow crazy ants have invaded numerous vulnerable islands, including the Johnson Atoll where they pose a significant threat to ground-nesting birds.
The average spreading speed of the supercolonies was calculated at 3m per day, the equivalent of 1. Having once got hold they never let go, but struggled and wrestled and rolled on the chips incessantly. Argentine ants are not unique in this behaviour, it has been observed in a number of invasive ant species and is referred to as a polygene colony.
The crabs are described as a keystone species that help to recycle detritus and replace nutrients in the soil, so any decline has a knock-on effect for the whole island. Wreaking financial havoc While some crops benefit from introduced ants, others can be destroyed.
The best known ant species have remarkable adaptations to their environments, such as the famous leafcutter ants that carry 50 times their bodyweight, fetching pieces of leaf to use as fertiliser for nourishing fungus.
Why here every ant was a Buttrick -- "Fire! Scientists point to these results as evidence that humans have actually fostered this family connection by repeatedly introducing Argentine ants from around the world to one another through global trade.The Battle of the Ants by Henry David Thoreau.
Please Note: The Battle of the Ants is not a stand-alone essay. It is excerpted from Thoreau's Walden Pond, Chapter Brute Neighbors, presented here as a convenience to students and instructors.
Argentine ants and big-headed ants meanwhile will enter homes in search of our oily, sweet foods. Both little fire ants and red imported fire ants prefer the open-air where the former nest in crevices and the latter build nest mounds on lawns and roadside verges. Studying the red and black ants fighting for no other reason that they hate each other, or one has taxed the other, brings Walden's passage to the point/thesis of the futility of war as well as the terrible waste.

Upon first glance, Henry David Thoreau’s “The Battle of the Ants” seems like a simple descriptive story of a battle between two different species of ants, one red and one black, but if one were to further inspect the text, they could see that Thoreau uses the ants and their battle as a.
